prokaryote- a cell without a visible nucleus eukaryote- a cell with a visible nucleus cell- the smallest unit of life cell wall- surrounds cell and provides structure and protection (found only in plant cells) cell membrane- outer covering of cell that allows nutrients to move in and out of the cell nucleus- the control center of a cell; contains DNA mitochondrion- converts nutrients into energy for the cell vacuole- storage 'bubble' inside cell that may hold water, nutrients or waste chloroplast- converts radiant energy from the sun into chemical energy the plant can use as food cilia- small, hair-like structures that help a cell move flagellum- a long whip-like structure that helps a cell move cytoplasm- the jelly-like liquid inside a cell in which organelles float autotrophic- an organism that makes it own food through photosynthesis heterotrophic- an organism that must get its nutrients from other organisms chromosomes- a piece of DNA that contains many genes structure- how something is made function- how something works or what it does DNA- deoxyribonucleic acid; the code found in the nucleus of every cell.
